Definitions

  • the present invention relates to a catheter pump intended for implantation and comprising an elongated sleeve through which a drive cable passes, the external end of which cable is connectable to an external drive source, the pump further comprising a drive rotor located in proximity to the inner end of the drive cable.
  • heart failure results in the heart pumping less blood to the body than that which the body requires in order to maintain vital functions.
  • Reduced heart muscle function can have many causes. The most usual is due to a heart infarction which can lead to temporary or chronic failure. Examples of other causes of chronic or temporary failure are myocarditis (heart muscle inflammation) , cardiomyopathy, metabolic diseases, poisonings, arrhythmia (irregular pulse) and many others. Also worth mentioning is temporary failure in patients after heart surgery and problems when stopping heart-lung-machine treatment.
  • PV hereby represents the pressure work per beat whilst 1/2 m v 2 denotes the blood acceleration work per beat.
  • the heart generates approximately one joule per beat.
  • a typical failure situation is when the blood pressure sinks to 80/50 and the beat volume to 30 ml. In order to compensate for this the heart increases its frequency to, for example, 130 beats/minute. Nevertheless, the heart work is only approximately 25-50% of the normal and this corresponds to heart power of approximately 0,25-0,5 Watt.
  • Hemopu p As pump principle the pump makes use of a rotary Archimedes screw which, via a metal cable in a catheter, is driven by an external electric motor. The catheter is inserted in the groin and introduced into the arteria femoralis with help of a small surgical insertion. It is thereafter led up into the aorta and a flexible needle is introduced through the aorta valves and sucks out blood from the left chamber to the aorta.
  • the catheter has been made as narrow as possible.
  • the needle in the left chamber has a diameter of approximately 7 mm and the Archimedes screw a diameter of around 3 mm.
  • the present invention thus relates to a catheter pump intended for implantation and comprising an elongated sleeve through which a drive cable passes, the external end of which cable is connectable to an external drive source, the pump further comprising a drive rotor located in proximity to the inner end of the drive cable.
  • the pump is characterized in that said drive rotor is in the form of an outwardly-foldable propeller. Because of the outwardly-foldable propeller, the catheter can be made very narrow, which is advantageous during introduction into the blood stream, but nevertheless provides a powerful flow effect in its outwardly-folded condition.
  • the catheter which should have a maximum diameter of 3-
  • the propeller can be placed in an arbitrary region of the aorta and can also be introduced into the left chamber.
  • the catheter In order to avoid the propeller, which can have a diameter of 1-2 cm, damaging the aorta, as described in the following the catheter should be provided with a lattice or bars which shield the propeller.
  • the bars When introduced into the left chamber, the bars can be provided with an elastic rubber sheath which prevents damage to the vital parts of the heart and which can also increase the pressure effect.
  • the pump or parts thereof In order to avoid thromboembolismic complications, the pump or parts thereof can be heparinized.
  • the pump is primarily intended for use in failure of the left chamber, but it is also conceivable that it be used for failure in the right chamber. It is conceivable that the pump be introduced via the vein system in the neck and into the right chamber or possibly in the arteria pulmonalis and thus with reversed rotational direction.
  • the above mentioned bars are suitably in the form of an expandable part adjacent the propeller.
  • This part can be in the form of filaments extending in the longitudinal direction of the sleeve.
  • the forward ends of these filaments are united at a common attachment which is arranged to be able to be displaced towards the propeller during the formation of a filament cage around the propeller. Said movement can be achieved through the attachment being attached to the drive cable, which is accordingly arranged to be axially displaceable for expansion of the filament cage.
  • Adjustment of the propeller also suitably takes place with help of the drive cable. It can thus be arranged to be folded out with the help of the drive cable, hence the drive cable being axially displaceable.
  • the drive cable can be in the form of a compact cable.
  • it can be in the form of an inner core with an outer sleeve axially displaceable with respect to the core.
  • a link mechanism can be attached to the propellor and to the core and outer sleeve respectively of the drive cable, the mechanism having such a construction that the propeller is folded outwardly by a relative sliding between the core of the cable and the outer sleeve.
  • the expandable part can be surrounded by a sleeve or a tube of an elastic material such as rubber or similar.
  • the drive cable is arranged to be rotated at a number of revolutions which is less than 10 000 rpm, preferably in the order of 3 - 5 000 rpm.
  • the propeller In its folded out condition, the propeller should have a work diameter of 10-20 mm, preferably about 15 mm.
  • the propeller is suitably arranged to be subjected to an effective pumping power in the order of 0,25-1 Watt, preferably about 0,5 Watt.
  • the propeller consists of a number of propeller blades individually carried on the drive axle which are arranged to be folded outwardly to their operational position due to centrifugal and/or pumping force during rotation of the drive axle.
  • the propeller blades are hereby suitably made to abut a propeller support mounted on the drive axle when the propeller blades are in their operational position.
  • the propeller blades can be locked between a propeller support mounted on the drive axel and a sleeve rotatable with the drive axle.
  • ADVANTAGES OF THE INVENTION - The entire construction can be made very thin for insertion and removal respectively, maximum diameter 3- 5 mm.
  • the pump can reverse its direction of rotation.
  • Fig. 1 is intended to illustrate the external dimensions of a catheter pump according to a first embodiment of the invention (scale 5:1).
  • Fig. 2 shows the same pump in its operational position.
  • Figs. 3-6 show sections according to lines III-III, IV-IV,
  • Fig. 7 schematically shows a second embodiment of the invention in its operational position.
  • Fig. 8 shows a part of Fig. 7 in rest position.
  • Fig. 9 shows a part of a third embodiment in its rest position.
  • Fig. 10 shows the part according to Fig. 9 in its operational position.
  • a first embodiment of the catheter pump according to the invention is shown in Fig. 2 in its operational position.
  • the pump comprises innermost a drive cable 1 which consists of an inner part la and an outer part lb.
  • the drive cable 1 is surrounded by an outer sleeve 2 which at its forward end merges into a cylindrical region 3 together with a plurality of filaments 4.
  • the drive cable 1 terminates with a round nipple 5 which serves both as a bearing and as an attachment for the filaments 4.
  • a link mechanism 6 an outwardly foldable propeller 7 is secured to the inner drive axle la.
  • the link mechanism 6 is schematically shown and can be modified in various ways in order to achieve the desired function.
  • the dashed lines 8 indicate that the lattice cage formed by the filaments 4 can be surrounded by an outer elastic sleeve of, for example, rubber.
  • the filaments 4 have been expanded to the position shown in Fig. 2 by means of a relative displacement between the drive cable 1 and its sleeve 2.
  • the propeller 7 has been folded outwards with help of the link mechanism 6 by means of a relative displacement between the two parts la and lb of the drive cable 1.
  • Fig. 3 shows a section along line III-III in Fig. 2, i.e. a section through the bearing nipple 5 and the attachment part 9 of the filaments 4.
  • Fig. 4 shows a section along line IV-IV in Fig. 2 and here it can be seen how the inner axle la can be surrounded by four filaments 4. This number can of course be varied.
  • Fig. 5 shows a section along line V-V in Fig. 2 and illustrates how the inner axle la is surrounded by an outer axle lb and the cylindrical extension 3 of the sleeve 2. These are all surrounded by the lattice cage formed by the filaments 4.
  • Fig. 6 shows a section along line VI-VI in Fig. 2 and illustrates how the inner axle la is surrounded by the outer axle lb and the sleeve 2.
  • Fig. 7 and 8 schematically show a simplified embodiment of the catheter pump according to the invention. In principle, however, it corresponds to the embodiment according to Figs. 1-6, and thus the same figure reference numeral have been used for corresponding parts, though with the addition of a prime.
  • the drive axle 1' here consists of a single solid part surrounded by the sleeve 2' .
  • the filaments 4' are in the same manner as described above secured to both the sleeve 2' and to a common forward section 9', which also serves as a bearing for the bearing nipple 5'.
  • the main difference with respect to the above described embodiment is that the blades or propeller 7' are here individually carried on a support part 10'.
  • Fig. 8 the blades are shown in their inwardly folded position. As soon as rotation is started they are automatically folded outwardly to their operational position shown in Fig. 7. This occurs due to both the centrifugal force and because the blades are so shaped that due to the pumping forces they are driven outwardly to their operational position. Folding in of the blades 7' can thus take place by reversing the rotational direction of the axle 1'.
  • Figs. 9 and 10 show a further modification of the catheter pump according to the invention.
  • This embodiment also corresponds to the above described, and so the same figure reference numerals have been used for corresponding components, though with the addition of a double prime.
  • the inner drive axle is thus denoted by 1'', a propeller support by 10'' and the propeller by 7''.
  • the inner drive axle 1'' is surrounded by an outer sleeve 2''.
  • a rotating displaceable cylinder 11" has been added which slides against the forward face of the sleeve 2'' which is provided with a slide bearing 12''.
  • the propeller 7'' is carried on the inner drive axle 1" by means of a bearing or link mechanism 6".
